I tried the Light Phone II but found it too limiting. While they did an admirable job trying to get functionality like maps usable it wasn't practical enough overall. Currently using the Unihertz Titan Pocket with the minimalist phone launcher as my daily driver.
This is a well known issue that has been posted on the Facebook groups and various reddit pages and from what I can tell, it has been around for at least a few years. It looks like it affects the Pocket and the Slim, although unclear if the original Titan is affected. I tried the various workarounds noted by Unihertz on the Facebook forum posts:
1. Moved next to router. The WiFi screen shows excellent -33 RSSI signal value
2. Settings } Apps & Notifications } Advanced } Special app access } Battery optimization } All apps
2a. System Wi-Fi Resources: Not optimized
2b. Tethering: Not optimized
2c. com.android.wifi.resources.overlay: Not optimized
2d. The app I was streaming video from
3. Settings } Intelligent assistance } App blocker } Off4. Ensured my router has different SSID for 2.4GHz and SSID for 5GHz networks
5. Connected phone to 2.4GHz network
6. Not running mesh mode
7. Disabled IPv6
8. WiFi authentication set to WPA2
